RF packaged multi-function circuits ease manufacturing

Hillsboro, Ore.TriQuint Semiconductor announced the availability of the first three packaged devices in its Multi-Function Circuit (MFC) family.

The MFC products, initially released as die-level devices in November 2006, are now available in industry-standard packages, offering what the company says is greater manufacturing flexibility for new and existing customers.

The high performance GaAs ICs were developed for use in point-to-point (PTP) radio and satellite communications applications. TriQuint's three newly packaged products address OEM needs for frequency upconversion (amplification) in the transmit (Tx) and local oscillator chains for digital radio and satellite communications systems.

Manufacturers can choose from a highly integrated module or separate discrete component functions to suit their individual assembly and PCB layout preferences.

The TGC4402-SM is a K-band upconverting mixer for digital radio and sat-com applications. This single-balanced passive product features single-ended signal ports; external RF, LO and IF baluns are not required.

The TGC4403-SM is a K-Band frequency doubler and includes a buffer amplifier. This digital radio and sat-com device delivers 20 dBm (typical) output power and 18 dB of gain. The amplifier's high conversion gain allows it to operate over a -5 dBm to +5 dBm input power range while consuming only 150mA of quiescent current from a +5V supply.

The TGC4405-SM is a K-Band single-balanced upconverter. This multi-function product for digital radio and sat-com applications features an integrated LO doubler and output post amplifier, providing 13 dB typical conversion gain across the 17-27 GHzRF band, with single-ended signal ports and integrated RF, LO and IF baluns.
